IMPROVEMENT IN SLATE-FRAME ATTACHMENTS- Specification forming part ofLetters Patent No. 191,009, dated May 22, 1877; application filed April2, 1877.

To all whom it may concern Be it known that I, KARL FRANK MEYER, ofAuburn, in the county Cayuga and State of New York, have inventedcertain new and useful Improvements in Attachments to Slate- Frames';and that the following is a full, clear, and exact description of thesame, reference being bad to the accompanying drawings, in which a slateand its frame having my improved attachments is representedin'perspectlve.

My invention relates to slates used by schoolchildren and others inconnection with slatepencils. When the slates, as heretoforeconstructed, are used in schools for exercises or calculations, it iscustomary, when recitations are to follow, to lay. the slates upon thedesk or shelf in the midst of books, from which they frequently fall tothe floor, make disturbing noises, and often become broken, although inmany cases, to' guard against these contingencies, they are providedwith elastic corners and other padding.

The object of my invention is to provide means by which the slate can besuspended under or at the side of a desk, or in any desired location, bymeans of a metallic eye or loop securely fastened to its frame; and itconsists in forming the base-plate of the metallic loop and the loopitself of a single piece of metal, and providing said base-plate withserrations upon which a slate pencil can be sharpened down to a finepoint.

In the drawings, A represents the slate, and B its frame, that can bemade of any desired form and construction. 0 represents a loop or eye bywhich the slate is to be suspended. This loop is formed with a largebase-plate, 0, so that its points of attachment to the slateframe at bcan be as far apart as possible, and not weaken or have a tendency tosplit the frame B, to which it can be secured by screws, clinched nails,or rivets. The base-plate O is provided with serrations upon whichslatepencils can be sharpened, if desired. It can be secured in themiddle of either side or end of the slate-frame, preferably in a recesscut out of the frame, so as to have its face even with the top of theframe. The loop 0 and its serrated base-plate are formed out of a singlepiece of metal, preferably steel, to resist abramom.

I am aware that serrated-steel pencil-sharpeners of various forms, suchas flat steel, V- shaped, hollow cylindrical, or conical, have beenused, either independently or attached to slate-frames, for the purposeof sharpening slate-pencils, and I do not claim any of these well-knowndevices.

What I claim as my invention is- As a new article of manufacture, aslateframe attachment consisting of a flat serrated base-plate, 0,provided with a loop, a, the said plate and loop being made in onepiece, and otherwise constructed substantially as described.
